HOWTO connect the Microchip enc28j60 module
===========================================
It's possible to to add Ethernet to most microcontrollers having a SPI inter-
face. In the Atmel world the SPI pins are used for the ISP programming. Usually
a 6-pin header. Named MOSI, MISO, SCK, CS (Chup Select), Vcc, GND
One popular Ethernet chip is Microchip ENC28J60. It been used for quite some
time and is easy to program and are also supported by many platforms and
projects. Contiki has files under:
Most focus fon AVR platforms. The SPI is used by Atmel ISP-progammings
interface. In addition to those pins you to selects a pin for chip
select (CS).
dev/enc28j60/
The low-level SPI drives is platform or rather CPU-specific. The avr-rss2
platform adds the low-level drivers for Atmel.
platform/avr-rss2/enc28j60_avr.[ch]
This should be usable on most 8-bit avr platforms.
The power consumption might be a problem. The enc28j60 consumes 160mA at 3.3V
when transmitting. The LDO (voltage reg. LP2950) on the mote can only handle
100mA. So external power is needed. Below is a description of a prototype.
Used components:
----------------
Externel power supply 5V.
Small breadboard
DC-jack
Voltage Reg. LCP1700 3.3V
Capacitor 4.7uF
enc28j60 (From Ebay)
Pin-headers
Cables 2x5 (enc28j60) 2x3 SPI (AtMega node)
Used colors:
Black GND
Red VCC 3.3V
Yellow SCK
Green MISO
White MOSI
Blue CS (Chip select)
SPI (Connector view)
--------------------
GREEN YELLOW NC
RED WHITE BLACK
CS is connected to external temp sensor middle pin. Consequently the
external temp sensor can not be used in this application.

Document version: 2016-02-22
An ethernet-to-802.15.4 NAT/GW IP64
===================================
This project is heavily based on the rpl-border-router in the example directory
using the IP64 framework. This work is done Contiki/Thingsquare as the driver
for enc28j60.
But rather than using slip as in the original example an ethernet interface
the Microchip enc28j60 is used. The needed SPI-glue for AtMega's is added by
this platform. (avr-rss2)
See the README.ETHERNET.md for ethernet module info.
